Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a rapid testing device for geological prospecting. Background Technology

[0002] Rapid detection equipment for geological prospecting refers to instruments and equipment used for rapid analysis and detection of elemental composition and content in geological samples in the field. These devices can provide accurate detection results in a short time, thereby improving prospecting efficiency. Common equipment includes portable X-ray fluorescence spectrometers. Portable X-ray fluorescence spectrometers are field analysis instruments based on X-ray fluorescence technology. They can quickly and non-destructively detect multiple elements in samples. Their working principle is to use incident X-rays emitted from an X-ray tube to excite atoms in the sample, causing their inner-shell electrons to jump and release secondary X-ray fluorescence with specific energy. By detecting the energy and intensity of these fluorescences, the instrument can determine the types and contents of elements in the sample.

[0003] When using a portable X-ray fluorescence spectrometer to detect minerals outdoors, the instrument probe needs to be aimed at the mineral surface. However, the outdoor environment is complex, and the mineral surface is often uneven, which can cause X-rays to pass through. The X-ray fluorescence generated by this passing through light can cause radiation damage to the staff. At the same time, the passing through light can cause some X-rays to pass through directly without fully interacting with the sample, resulting in weakened or interfered X-ray fluorescence signals. This signal weakening reduces the detection sensitivity, making it difficult for the instrument to accurately identify and quantify the elements in the sample. Therefore, a rapid detection device for geological prospecting is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid detection device for geological prospecting, in order to solve the problems of complex outdoor environments and uneven mineral surfaces, which can lead to X-ray transmission. The X-ray fluorescence generated by this transmission can cause radiation damage to workers. At the same time, the transmission can cause some X-rays to penetrate directly without fully interacting with the sample, resulting in weakened or interfered X-ray fluorescence signals. This signal weakening reduces the detection sensitivity, making it difficult for the instrument to accurately identify and quantify the elements in the sample.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A rapid geological prospecting detection device includes an X-ray fluorescence spectrometer 1 and a detection head 2. An external block 3 is fixedly connected to the outside of the detection head 2, and a sealing and protection component 4 is installed on the inside of the external block 3. The external block 3 includes a sleeve 31, and a guide air hole 32 is opened on the inside of the sleeve 31. A spring 33 is fixedly connected to the rear end of the guide air hole 32. The sealing and protection component 4 includes a protective cover 41, and an air guide channel 42 is opened on the inside of the protective cover 41. A double column cylinder 43 is fixedly connected to the rear end of the protective cover 41. A first rubber sealing ring 44 is fixedly connected to the outside of the double column cylinder 43. A connecting groove 45 is opened on the inside of the double column cylinder 43. An airbag ring 47 is fixedly connected to the front end of the protective cover 41. A second rubber sealing ring 46 is fixedly connected to the inside of the protective cover 41. The double column cylinder 43 is slidably connected to the inside of the guide air hole 32.

[0029] As a further implementation of this scheme, the front end of the X-ray fluorescence spectrometer 1 is fixedly connected to the rear end of the detection head 2, and the inner side of the sleeve 31 is provided with a mounting hole. The outer side of the detection head 2 is fixedly connected to the mounting hole on the inner side of the sleeve 31. Through the above settings, the overall structural stability of the device is ensured, and the reliability and accuracy during detection are improved.

[0030] As a further implementation of this scheme, the guide air hole 32 is shaped as two cylinders of different diameters. The guide air hole 32 penetrates the front end of the sleeve block 31. There are two guide air holes 32. The double column cylinder 43 is shaped as two cylinders of different diameters. The connecting groove 45 penetrates the inner side of the double column cylinder 43 from front to back. The connecting groove 45 is connected to the guide air hole 32. The front end of the spring 33 is fixedly connected to the rear end of the double column cylinder 43. The outer side of the first rubber sealing ring 44 is in contact with the inner side of the guide air hole 32. The double column cylinder 43 extends out of the front end of the guide air hole 32. The number of double column cylinders 43 is the same as that of the guide air hole 32. Through the above settings, air can enter the interior of the guide air hole 32 through the connecting groove 45, and then enter the air bag ring 47 through the air guide channel 42, realizing the expansion and contraction of the air bag ring 47, effectively sealing the gap between the mineral and the device, preventing the X-ray fluorescence signal from weakening or being interfered with, and improving the sensitivity and accuracy of detection.

[0031] As a further implementation of this solution, a gap is provided between the protective cover 41 and the sleeve block 31. The protective cover 41 is sleeved on the outside of the detection head 2, and the inner side of the second rubber sealing ring 46 is in contact with the outside of the detection head 2. The inner side of the protective cover 41 is a hollow structure, and the detection head 2 extends into the interior of the protective cover 41. Through the above arrangement, space is provided for the movement of the protective cover 41. The arrangement of the second rubber sealing ring 46 can prevent X-ray fluorescence from leaking out from between the detection head 2 and the protective cover 41.

[0032] As a further implementation of this solution, the air duct 42 penetrates the inner side of the protective cover 41 from front to back, and the connecting groove 45 is connected to the air duct 42. The rear end of the airbag ring 47 is a hollow structure, and the air duct 42 is connected to the rear end of the airbag ring 47. Through the above settings, the structure of the air duct 42 penetrating the protective cover 41 and the connection design of the connecting groove 45 and the air duct 42 ensure that air can smoothly enter the interior of the airbag ring 47, realizing the expansion and contraction of the airbag ring 47.

[0033] Workflow: During geological testing, the operator holds an X-ray fluorescence spectrometer 1, aligns the sealing and protective assembly 4 with the mineral to be tested, and pushes the X-ray fluorescence spectrometer 1 towards the sealing and protective assembly 4. The X-ray fluorescence spectrometer 1 drives the external block 3 and the detection head 2 to move towards the sealing and protective assembly 4. At this time, the detection head 2 gradually moves towards the front end of the protective cover 41, getting closer to the mineral. As the sleeve block 31 moves towards the sealing and protective assembly 4, the double-column cylinder 43 slides back inside the guide air hole 32, compressing the spring 33. The elasticity of the spring 33 resets the double-column cylinder 43. As the double-column cylinder 43 moves into the guide air hole 32, the air inside the guide air hole 32 enters the air guide channel 42 through the connecting groove 45. The air guide 42 enters the interior of the airbag ring 47, at which point the airbag ring 47 expands. After expansion, the airbag ring 47 seals the gap between the mineral and the device, thereby preventing external light from entering the interior of the protective cover 41. This prevents the X-ray fluorescence signal from weakening or being interfered with, thus reducing the detection sensitivity. At the same time, when the X-ray fluorescence spectrometer 1 emits X-ray fluorescence through the detection head 2, it prevents X-ray fluorescence from leaking out of the protective cover 41, preventing X-ray fluorescence from causing radiation damage to the staff, improving the safety of use and the accuracy of the detection results. After the detection is completed, the device is moved away from the mineral. When pushed by the spring 33, the double column cylinder 43 moves out from the inside of the guide air hole 32. At this time, a negative pressure is generated inside the guide air hole 32. Under the action of the negative pressure, the airbag ring 47 contracts, facilitating the detection of the mineral.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
